How to use CC_MD5 method in swift language

Question

in Objective-c, we can hash a string like this:

const char *cStr = [someString UTF8String];
unsigned char result[16];
CC_MD5( cStr, strlen(cStr), result );
m

I am calculating MD5 hash, but using only the first 16 byte I am using

class func hash(data: NSData) -> String {

    let data2 = NSMutableData(length: Int(CC_MD5_DIGEST_LENGTH))!
    CC_MD5(data.bytes, CC_LONG(data.length), UnsafeMutablePointer(data2.mutableBytes))
    let data3 =  UnsafePointer(data2.bytes)

    var hash = ""
    for (var i = 0; i < 16; ++i) {

        hash +=  String(format: "%02X", data3[i])
    }

    return hash
}
